B1A4, who appeared on the ‘7 Minute Invitation’ corner of MBC Radio ‘Park Kyunglim’s Starry Night’ on the 3rd, perfectly did a live of their own title song, ‘O.K’.

The ‘7 Minute Invitation’ in ‘Starry Night’, B1A4’s first ever radio, has appearances from rookies during one week for 7 minutes. During this time, they do one live song and a short talk session causing this corner to be a gateway for rookies.

Also, it looked like they were enjoying the broadcast through the viewable radio, making it almost hard to believe that it’s their first radio appearance. Leader Jinyoung sang one line from the song, ‘Bling Girl’, which he participated in composing and writing the lyrics for.

Meanwhile, B1A4, who didn’t fill up the contentment as only Jinyoung’s profile was introduced during ‘Park Kyunglim’s Starry Night’ (95.9MHz), is appearing again on the 4th and 6th. They plan to show a different live performance and more short talk sessions.
